Cinnabar – Mercury Sulfide Powder

Posted on by adminLeave a comment

A fine, bright-scarlet powder that is deadly if ingested.

Mercury sulfide is also known as cinnabar and metacinnabar, and is used as a pigment in paints and sealing wax. It is obtained by heating mercury metal with elemental sulfur, and also by the addition of zinc powder to accelerate the reaction.

It is stable under normal conditions, but not incompatible with acids and strong oxidizing agents. It also does not react with halogens or metal oxides.

The black form of mercury sulfide is prepared by passing hydrogen sulfide into a solution of HgCl2 with the formation of a pale yellow precipitate, which then converts to amorphous black HgS on further treatment with H2S.

In nature, the red form of mercury sulfide is found as a-HgS (hexagonal, hP6, P3221), which is optically active due to its helices in the crystal structure. Alternatively, the black form of mercury sulfide may be produced by the reaction of hydrogen sulfide with the b-HgS of mercury.

Cinnabar is the common name for mercury sulfide and can be extracted from a variety of ores. It is an odorless, solid, red or black mineral that can be crushed and ground to produce a fine powder of brilliant scarlet color.

Cinnabar is poisonous if swallowed and should not be handled by children. It should be stored in a cool, dry place and should not be disposed of without proper protection. This product can be used as a color pigment in paints, but it should not be mixed with other dyes.

    boron sulfide is a yellow to white crystalline solid, other names are B2S3 and boron trisulfide. It turns into a paste after heating and resolves in moist air. It is faintly soluble in phosphorus trichloride, sulfur dichloride and alcohol and tends to hydrolyze.

    It is a good antiseptic and is used in eye lotions, in solutions for electroplating nickel, or in tanning leather. It is also a good catalyst in many organic chemical reactions.

    When boric acid is heated, it loses water to form metaboric acid, HBO2. Then, further loss of water results in the formation of boron oxide, B2O3. It has many industrial applications including as a mild antiseptic for burns and surface wounds, as a fire retardant in fabrics and in solutions for electroplating nickel or for tanning leather.

    Unlike most sulfides, it can be dissolved in water (hence its name).

    It is about twice as soluble as carbon dioxide.
    It can be found in a variety of foods and is an important component in some medicines. It is toxic to mammals and is about half as flammable as hydrogen cyanide.

    When you breathe hydrogen sulfide, it smells like rotten eggs and it kills you. The strong smell and the fact that it has no taste make it a great poison.

    Introduction to Zinc Sulfide ZnS Pulver Zinc sulfide An inorganic compound having the chemical formula ZnS. It is a powder with a yellowish color that darkens upon exposure to sunlight. It is stable when dry, but it will slowly oxidize to zinc sulfurate over time if left in humid conditions. It is most often formed by the reaction of hydrogen sulfide in zinc salt solution. Zinc sulfuride has a high fluorescence effect as well as an electroluminescence function. In particular, nano zinc sulfide has a unique and powerful photoelectric effect and is a great asset in the fields electricity, magnetism mechanics and catalysis.

    Zinc Sulfide ZnS Pulver: Physicochemical Characteristics
    Covalent is the most common chemical bond between Zn sulfide and S zinc sulfide. Three types of crystal are available: Low-temperature type, which is the sphalerite crystal that is found abundantly in nature, and colorless cubic crystal. The Zn S coordination number is 4 and the relative density is 4.10. It will transition to high-temperature at 1020. It is a high-temperature zinc sulfide stable structure. The sodium chloride type, which is Zn, S number are 6, has a relative density of 5.21. The aqueous compound ZnS*H2O also exists, which is a white powder having a relative density of 3.98 with a melting point 1049. Zinc sulfuride is insoluble and insoluble with water and dilute acid. It is also insoluble and insoluble when acetic acids are present. However, it can be dissolved in low concentrations in strong acids, such as hydrochloric, which releases hydrogen sulfide. The solubility of zinc sulfide resembles the K1*K2 value for hydrosulphuric Acid, so there is the following equilibrium in dilute acid.
    Zn2+H2S=2H+ZnS
    It is clear that zinc sulfide can not be precipitated in highly acidic solutions of zinc salt. When hydrogen sulfide gases is added to zinc salt solution, zinc sulfide precipitation may be possible, but it is not complete. Ammonium sulfide can be used as a precipitant to precipitate zinc ions from zinc salt solution. The alkaline nature of ammonium solution allows for the reduction in the acidity. This method is used to separate air in industry. When exposed to light, white zinc sulfide turns dark and can easily be oxidized to zinc oxide in air. Zinc sulfuride can be used in white paint pigments by itself or with zinc oxide. Pure zinc sulfide does not emit light. As activators, zinc sulfide crystals can emit different colors after light irradiation. Zinc sulfide has many uses in leather, rubber, dye, and other industrial sectors.

    The chemical formula for zinc sulfide is ZnS.

    Zinc sulfide occurs naturally in the form of the mineral sphalerite, but it can also be synthesized. When heated to a temperature of 102 degC, the stable beta crystalline form of ZnS changes into the alpha form (wurtzite).

    Besides being used as an optical material for visible light and infrared light, zinc sulfide can be shaped into lenses and optics, or even planar windows. Its transparent nature makes it an excellent choice for luminous dials.

    Phosphorescent materials can be prepared by combining different activators with zinc sulfide. Its phosphorescence is a useful property for a variety of ornamental and electrical applications, from cathode ray tubes to glow-in-the-dark products.

    The simplest method of preparing ZnS for phosphorescent purposes is to dope it with a suitable activator, such as sulfur vacancies. After that, it can be used for making phosphorescent paints and other decorative materials.

    Another way of preparing ZnS is to recombine it with a base such as sodium sulfide to form an electroluminescent material. This can then be used for a variety of applications, including the production of color TV and monochrome television displays.

    The phosphorescent property of zinc sulfide can be made more prominent by adding a small amount of barium sulfate, which is known as lithopone. This is a very common pigment that can be found in many types of paints and rubber, as well as plastics.

    The specific gravity is 1.66 (water = 1); the melting point at 938degC is 938degC and the boiling point at 1372degC are both 1.66.
    Water soluble, soluble, ethanol soluble, soluble, acid soluble, insoluble, alkali insoluble.
    Chemical nature
    Lithium sulfide is able to absorb water vapor from the air and hyrolyzes, releasing highly poisonous hydrogen sulfide.
    Separating lithium sulfide with acid can liberate hydrogen sulfuride. It can also react violently to nitric acids, but it can only be decomposed by heating it. Hydrobromic acid or hydroiodic can do this. It reacts slowly and violently with concentrated sulfuric, but not with dilute. When heated to around 300°C in air, it becomes oxidized by oxygen but doesn’t produce sulfur dioxide. Instead, it produces lithium sulfate.

    Preparation for lithium sulfide
    You can prepare lithium sulfide in a number of ways. The preparation of lithium sulfide was possible in the past by heating sulfur and lithium together. In order to produce lithium sulfide, carbon or hydrogen were used under heat to reduce the lithium-sulfate. It was later discovered that lithium and sulfur could act together in liquid ammonia. Or, lithium ethoxide may decompose lithium hydrosulfide’s ethanol adduct to create lithium sulfide. Some people then combined hydrogen sulfide with lithium pentoxide in order to first prepare lithium hydrogen, sulfide. Next, the vacuum heating was used to decompose lithium hydrogen, sulfide.
    Anhydrous lithium sulfide is a high-quality product that can be made by reacting metallic lithium and hydrogen sulfide with tetrahydrofuran.
    Application of lithium sulfide
    Lithium sulfide is mostly used as an electrolyte in rechargeable lithium ion batteries.
    Precautions and storage of lithium sulfide
    Lithium Sulfide is able to absorb water vapor from the air and hyrolyzes it, releasing highly toxic hydrogen sulfuride gas. It must be kept at room temperatures in a dry, dark area.
    Hydrogen sulfuride can cause slight harm to water bodies. Do not expose large amounts or undiluted products to groundwater or sewers.
